    摘要： Disclosed is an evaporated fuel feed control device for use in an internal combustion engine which comprises a charcoal canister and an evaporated fuel feed control valve. The feeding operation of the evaporated fuel is stopped only when the throttle valve is closed while the engine is operating at a high number of revolutions per minute, as in the case wherein the vehicle is decelerated while being driven at a high speed.

    摘要： A switching power supply circuit includes a PWM drive circuit (12) that performs the PWM driving of a switching element (Q1) at a duty ratio (D) commensurate with an input target voltage (VS), and generates from an input voltage (VB) an output voltage (VTL) whose target value is the target voltage (VS), by the PWM drive circuit (12) driving the switching element (Q1). The switching power supply circuit further includes a control circuit (13) and a target voltage limiting circuit (14) that together fix the duty ratio (D) regardless of the target voltage (VS), when a difference between the input voltage (VB) and the target voltage (VS) is less than or equal to a predetermined constant value (α).

    摘要： A voltage conversion device includes: first and second loop circuits having a common inductance element. Electric current alternately flows through the first or second loop circuit as a first switching element of the first loop circuit is turned on or off. A magnetic field that is formed when the first switching element is turned on and that penetrates through the first loop circuit and a magnetic field that is formed when the first switching element is turned off after it is turned on and that penetrates through the second loop circuit have the same direction. All elements that constitute the first and second loop circuits are arranged on the same surface of a substrate. The second loop circuit is connected to a second direct-current power source. The first loop circuit is connected to a first direct-current power source.
